Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3198, here are decompositions:
- 7 + 3191 = 3198
- 11 + 3187 = 3198
- 17 + 3181 = 3198
- 29 + 3169 = 3198
- 31 + 3167 = 3198
- 61 + 3137 = 3198
- 79 + 3119 = 3198
- 89 + 3109 = 3198
Showing the first eight; more decompositions exist.
